Okay she is cute but she doesn't act like qn adult in a child's body. I forgot hoe old she was before tranograiton and reincarnation so if she was like 10 or 12 then fine. If she was 16 or over , this is too weird. The way she knows the story's plot and how everyone is out to get the kids yet keeps wondering around and putting herself in major danger...shr also pretty much never did anything useful aside from using her power....now I get that she just became 3 and I don't expect her to be some ninja martial artist but the least she could do is use her mind to do things and plan for the future. Unless the author explicitly states that her mind regressed or something...she is not using the fact that she is a transmigrator at all which is the whole charm or such a story. I would never read a story with a regular toddler MC
